Bandwidth on Demand Deliverables

This document describes the design specification for the IDM module prototype of the Bandwidth on Demand system developed by the GÉANT2 JRA3 activity. The prototype is a proof of concept of the design, information flow control and reservation processing on both inter-domain and intra-domain levels with an initial focus on the Inter-Domain Manager (IDM). The scope of this work is to implement and test the key modules and functionalities, which need to be studied before building a fully operational system. However the prototype is engineered so as to comprise the basis for further system development. It has been designed as a test machine, to allow easy discovery of system weaknesses and potential problems at the early stages of the system development. In the first part of the deliverable, the building blocks of the prototype as organized in packages and classes are documented in full detail, while in the second part the relationships between classes/objects are documented using sequence diagrams.

The Bandwidth on Demand service, as defined in the context of the GN2 project, aims at providing a guaranteed capacity, connection oriented service between two end points. The overall BoD service architecture is described in Deliverable DJ3.3.1, 'GÉANT2 Initial Bandwidth on Demand Framework and Architecture'. This deliverable specifies a key module of the JRA3 BoD system: the Inter-Domain Manager. Part A reports its functional specifications and Part B its implementation specifications with specific details for its first release, named as Prototype or Phase 0. The Pathfinder algorithms specifications are still in a draft stage and are not detailed. The abstract notation specification is detailed, and a subset will be implemented in the IDM prototype. A fast prototyping cycle of the implementation is currently underway in order to evaluate open issues and validate the specifications

The Bandwidth on Demand service, as defined inthe context of the GN2 project, aims at providing a guaranteed capacity, connection oriented service between two end points. the deliverable elaborates on a technical framework and draft architecture for the service to be deployed in a large multi-domain network with multiple transport technologies. This document outlines a BoD service architecture, which is sufficiently detailed to allow the first phase of implementation using manual or semi-automated procedures. It is expected that refinement and improvements will result from the feedback of the implementation experience.

The objective of this deliverable is to present a comprehensive study of the state-of-the-art of technologies related to the provision of Bandwidth-on-Demand services and to examine their feasibility for use within the GN2 project.
